Description

n-Butane-2,2,3,3-D4 is a deuterated isotopologue of n-butane, where four hydrogen atoms are replaced by deuterium atoms at the 2 and 3 positions, making it a valuable labeled compound for research and analytical applications. This high-purity standard is essential for applications requiring precise molecular tracking and spectroscopic analysis due to its isotopic purity and defined structure. It is primarily utilized by researchers and analytical laboratories in the fields of NMR spectroscopy, mass spectrometry, reaction mechanism studies, and as an internal standard in quantitative analysis.

Application

• NMR Spectroscopy: Serves as a chemical shift reference and solvent for deuterium NMR studies.
• Mass Spectrometry: Used as an internal standard for the accurate quantification of butane and related hydrocarbons.
• Reaction Mechanism Studies: Acts as a tracer to elucidate reaction pathways and kinetic isotope effects in organic and catalytic chemistry.
• Analytical Reference Standard: Provides a certified reference material for calibrating instruments and validating analytical methods in petrochemical and environmental testing.
• Deuterated Solvent Production: Can be used as a precursor or intermediate in the synthesis of other deuterated solvents and compounds.
• Fundamental Research: Employed in physical chemistry for studying molecular dynamics, vibrational spectroscopy, and thermodynamic properties of isotopically labeled molecules.
